Review: Samsung Instinct

I've just purchased the Instinct and I'm shocked that the security is so lame. Please help me. Touch phones only allow you to lock the complete phone or have your information openly accessible? WTF!!!! So if my phone is lost or my girlfriend sees my phone which this phone is so attractive you are gonna want to play with it. My contacts, text messages, pics, and every personal info is exposed to the public. I would expect samsung, apple, blackberry and any other high end phone to have better security functions. This alone will make me return this phone. Am I over exagerating? I feel its a principle. You pay for something and input all of your confidential info and either the phone is completely locked or completely open.
